Professional Applications & Engineering Value

This thick-wall stainless steel threaded pipe nipple is engineered to address critical challenges in industrial fluid and gas handling systems. The seamless 316/316L stainless steel construction eliminates weak points, providing exceptional resistance to pitting and stress corrosion cracking when exposed to aggressive media like hydraulic fluids, steam, and natural gas. With a Schedule 80 wall thickness and NPT threaded ends, it maintains pressure integrity in high-vibration environments, preventing system failures in petrochemical, power generation, and water treatment plants. The precise 48-inch length and standardized threading ensure compatibility with existing 3000-class fittings, reducing downtime during retrofits or repairs while meeting rigorous ASME and ASTM specifications for reliability.

Specification Summary & Compliance

This pipe nipple adheres to ASME B1.20.1 for NPT thread dimensions and ASTM A733 for seamless pipe standards, ensuring Class 2A thread tolerances for leak-free performance. Key dimensions include a 1.278" ID, 1 21/32" OD, and 0.191" wall thickness per Schedule 80 requirements. It is fully RoHS 3 (2015/863/EU) compliant and suitable for use with air, hydraulic fluid, natural gas, oil, steam, and water in industrial applications.
